《python基础笔记4》序列化和json

一、序列化数据

  引入pickle包

  dumps进行序列化，loads进行反序列化

1、序列化列表

# coding=utf-8
import pickle
status_list = ["one","two","three"]
pickle_data = pickle.dumps(status_list)
new_status_list = pickle.loads(pickle_data)
print new_status_list[1]

输出结果：two

2、序列化字典

# coding=utf-8
import pickle
status_list = {"one":100,"two":200,"three":300}
pickle_data = pickle.dumps(status_list)
new_status_list = pickle.loads(pickle_data)
print new_status_list['one']

输出的结果：100

二、json数据

引入json包，使用dumps和load进行encode和decode

1、列表数据转为json

import json
status_list = ["one","two","three"]
json_data = json.dumps(status_list)
new_status_list = json.loads(json_data)
print new_status_list[1]

输出结果:two

2、字典数据转为json

import json
status_list = {"one":100,"two":200,"three":300}
json_data = json.dumps(status_list)
new_status_list = json.loads(json_data)
print new_status_list['one']

输出结果：100
